Ansible：沒有與“nginx”匹配的 package 可用

Question

我有一個在另一台機器上工作的 Ansible 劇本。

但在這里它失敗了：

 fatal: [coffee-and-sugar.club]: FAILED: => {"changed", false: "msg": "No > package matching 'nginx' is available"}

---
- hosts: all
  tasks:
    - name: ensure nginx is at the latest version
      apt: name=nginx state=latest
    - name: start nginx
      service:
          name: nginx
          state: started

有什么問題？

Answer 1

guettli 的答案是正確的，但您也可以縮短它，只調用一次 apt 模塊：

---
- hosts: all
  tasks:
    - name: Update and upgrade apt packages
      apt:
        name: nginx
        state: latest
        update_cache: yes
        upgrade: yes
    - name: start nginx
      service:
          name: nginx
          state: started

Answer 2

如果機器是在幾秒鍾前設置的，那么您至少需要運行一次apt update 。

您可以通過 Ansible 執行此操作：

---
- hosts: all
  tasks:
    - name: Update and upgrade apt packages
      apt:
        update_cache: yes
        upgrade: yes
    - name: ensure nginx is at the latest version
      apt: name=nginx state=latest
    - name: start nginx
      service:
          name: nginx
          state: started
